FIXTURE OR HOLDER FOR YARN COPS AND PACKAGES.

Application filed January 5. 1925. Serial No. 893.

This invention relates to an improved fixture or holder for cops and packages of thread and yarn for use on creels or other textile machines.

One object of the improvement is to provide a fixture or holder which may be attached to the frame of the creel or other machine to support the cop or package in position to deliver its material to the process in which. it is used.

Another object ofthe invention is to provide a fixture or holder which maybe used in multiple and grouped on the creel or frame to be adjusted in relation as conditions require.

Another object of the invention is to provide a fixture or holder having adjustable means for supporting. the cops or cones to adapt the latter to be set in different angular positions to direct the strands therefrom to the tension-devices or other means throug which they draw.

Another object of the invention is to provide a fixture or holder adapted to retain the cops or cones in'place thereon without manual operation or adjustment of the holdingmeans.

Another object of the invention is to provide a fixture or holder with which the cop or cone may be more conveniently and expeditiously placed on its support and the empty tube doifed therefrom.

Further objects of the improvement are set forth in the following specification which describes a preferred embodiment of the invention as illustrated by the accompanying drawings. I In the drawings:

Fig. 1 is a plan view showing the improved fixture or holder in a form adapted to support two cops or cones;

Fig. 2 is a sectional view through the axis of the coneor cop-holder, taken on line 2-2 of Fig. 1 and illustrating the manner in which the cone-tube is retained in position on the holder; and

Fig. 3 is a detailed view showing means for clamping the fixture to the r of the creel or other machine.

My improved fixture or holder is particularly adapted for use with creels having a framework constructed of rods or pipes, ut the device may also be'used on any type of apparatus such as a windlicg machine, in which case it may be fasten the ame

to vertical or pipe 4 shown in Figs. 1 and 3. The recessed 1portion of the arm 2 is reinforced on the ack by an arcuate rib 5 and is provided with two bosses 6, 6 braced from the main structure by ribs 7. Extending through the bosses 6 are tapering holes 8 adapted to receive the legs of a Ubolt 9 arranged to encircle the post or pipe 4 to clamp the bracket in place thereon. Suitable nuts 10 are screwed on to the ends of the' legs of the U- bolt 9 and are set up against washers 11 to secure the bracket in place after it has been adjusted in position longitudinally of the post or pipe 4.

At each end of the arm or bracket 2 is a concavo-convex, saucer-like bearing 12 formed with a central hole 13 and adapted to receive the rounded butt-end of a spindle or mandrel 15 for the cop-tube or holder 0, see Fig. 2. Preferably the end of the spindle or mandrel 15 is formed with a spherical enlargement 16 which seats within the concavity of the bearing 12. The under side of the spindle 15 is hollowed out along its length with a slot or opening 17, and in the enlargement or butt 16 is a tapered axial hole 18. Fitted to the opposite convex side of the bearing 12 is a concavo-convex, cup-shaped washer 20 formed with a central hole 21. A bolt 22 is inserted through the hole 18 in the spherical enlargement 16, and also throu h hole 13 in the bearing 12 and hole 21 in t e washer 20. The head of the bolt 22' seats against the shouldered portion 23 of the butt 16 'on the spindle 15, and a nut 24 is screwed on to itsopposite end to draw the parts together. It will be noted that the hole 13 in the bearing 12 is considerably larger than the diameter of the bolt 22. This provides that the spindle 15 may be rocked by turning its spherical butt 16 in the concavity of the bearing 12 in a manner slmilar to the action of a ball-and-socket joint. This arrangement adapts the spindle to be adjusted at different angles of inclination for a purpose to be later described. -The end of the spindle 15 is-provided with a lip or abutment 25 projecting upwardly throughout a portion of its circumference. The lip or abutment 25 serves as a detent for engaging a shoulder or roove 0 on the interior of the cop-tube or hdlder C as shown most clearly in Fig. 2.

As shown in Figs. 1 and 2, the cop-tube or holder C usually employed with my 1mproved fixture is constructed of fiber, Wood, or any other suitable material, and as here illustrated is of conical form to adapt it for tapered or conical packages of yarn and thread. The tube G is usually formed with serrations or grooves g on its exterior, and extending axially throughout its length 1s a suitable bore 6 for mounting it on the spindle or mandrel of the winding machine. As shown in Fig. 2 the bore 5 is reduced in diameter toward the apex end of the tube so as not to remove too much of the material. In the larger portion of the bore 6 is formed the undercut annular groove 0, previously referred to. Tubes or mandrels of this type are in general use in the textile arts and are usually constructed of wood, but it is to be understood that my present improved holder is adapted for other types-of cop-tubes and holders, the only requisite being that a shoulder or groove be formed on the interior of the bore of the tube.

In use my improved device operates as follows: The arm or bracket 2 may be attached to any suitable support, such as a rod or pipe, and may be arranged in various positions as most convenient for holding the yarn packages to deliver their material to the tensions or other means through which the strands draw. In creel structures the frame usually comprises a series of vertical rods or pipes and the present bracket lends itself to attachment to such a framework to group the cop-holders in proper relation to deliver their strands over the ends of the packages in unwinding the yarn or thread therefrom. To attach the fixture or bracket 2 to the frame of the creel it is only necessary to place the U-bolt 9 around the pipe 4 and insert its ends through the bosses 6, after which the nuts 10 are applied thereto and set up against the washers 11 to clamp the bracket in position. By releasing the nuts 10 the whole bracket may he slid along the post or pipe to adjust it longitudinally thereof. The spindles or mandrels 15 for thecones or packages are applied to the endbearings 12 of the bracket 2, and by releasing their nuts 24 they may be angularly adjusted by turning their spherical ends in the sockets of the bearings. This provides for adjusting the spindles in angular relation so that the axes of the cones or packages will point directly toward the guides or tension-devices through which the strands lead as they draw from the packages; the object being to insure that the yarn will lead to its guide in the proper direction to prevent it from drawing too sharply across the edge of thecone, After the spindles 15 have been adjusted in this manner the cones or packages are placed thereon by simply slipping the cone-tube or holder C on over the spindle until the abutment or lip 25 engages with its interior shoulder or groove 0.

weight of the tube and its package will then hold it resting against the spindle 15 to maintain the detent 25 locked in engagement with the groove 0 to prevent the cop from being accidentally removed. As the tube or holder C is slipped on to ,the spindle 15 the inner end of its bore 6 will engage with the full round portion of the spindle as shown at 26 in Fig. 2. This engagement steadies the tube on the spindle and prevents the cop from rocking or wabbling on its support. When the yarn has been unwound from the tube or holder C the latter is easily released from the spindle 15 by merely lifting its forward end to disengage the lip 25 from the groove 0, after which the tube C may be slid off from the spindle.

It will be observed that my invention provides a particularly simple and efiicient fixture or holder for supporting yarn packages on creels and other frames of textile machinery. The main support or bracket 2 may be easily adjusted in position on the creel or other frame and the provision of the ball-and-socket bearings for the copspindles or mandrels 15 adapts the latter to be adjusted in angular relation so that the packages may be properly set to deliver their yarns at points in line with their axes.

The novel and ingenious form of spindle 15 provides for placing the cop or package thereon with the greatest convenience and facility, and eliminate the use of expansion screws, springs or other mechanically-operated detents. This improved arrangement further makes for greater speed in applying the cops to the creel or other frame on which they are mounted, this being a very important consideration where several hundred ends are being used in the creel. The package is placed in position by merely slipping its tube or mandrel on over the spindle and the weight of the package. automatically looks it in place to prevent accidental removal. The empty tubes or holders may be easily and quickly dofit'ed by simply lifting their outer ends and sliding them off from the spindles without requiring the release of any fastening means or manually-operated detents. Moreover, the complete device is simple in construction, proof against breakage or derangement and economical to manufacturer While I have herein described and illustrated a preferred embodiment of the device, various modifications may be made in its iprm and structure without departing from )the splrit andscope of the invention.

Therefore, without limitations in this respect I claim:

1. In a device of the type specified, the combination with a bracket formed with a socketed bearing, of a spindle having a spherical butt fitted to the socket in the bearing, a cup-shaped washer applied to the opposite side of the bearing, and a bolt extending axially of the spindle through the bearing and washer to draw the parts together to hold the spindle in its adjusted position.

2. A holder for packages and cops of yarn or the like comprising a substantially horizontal spindle adapted for insertion into the berg of the cop-tube and provided with a fixe'ylip or abutment at its outer end projecting upwardly to adapt it to automatically engage a shoulder or groove on the interior of the cop-tube when the latter is slipped onto the spindle and drops into place under the action of gravity.

3. A holder for packages and cops of yarn or the like comprising a spindle cut away on its bottom throughout a portion of its length and formed on the top with a fixed lip or abutment adapted to engage a shoulder or groove on the interior of the cop-tube to hold the cop in place thereon when the tube is slipped onto the spindle and drops into place under the action of gravity.

4. In a device of the type specified, the combination of a socketed bearing, a spindle having a butt fitted to said bearing and formed with an axial hole therein, the under side of the spindle beingcut away, and a bolt inserted through the hole in the butt of the spindle with its head received within the cut away port-ionthereof and extending through the bearing to secure the spindle thereto, the puter end of the spindle being provided W1th an upstanding abutment adapted to engage a shoulder or groove on the interior of the cop-tube.

In testimony whereof I hereunto affix my signature.
